I think I have read too many books involving ghosts (or read about them) I kept wondering if the sentinel here was a hottie and if they would hook up ;)Let us forget about that and get to the story. Verity is an archaeologist, she loves her job but wants back to digging. So in comes Scotland, and a mysterious job she knows nothing about. Plus an ex-boyfriend who tells her to come. She has a logical mind, she likes order, but it does prove that she has an open mind too. For that I liked her, sometimes you just have to believe (well after a while). On the team is also the eccentric boss who wants to find the missing Ninth Legion. Her ex-boyfriend who loves them and leaves them. A Scottish archaeologist who she starts to fancy. A woman who works at the estate and of course her son, the son who says he can see a Roman Sentinel guarding the hill. A nice group of people all in all.The book is part fiction, part tiny bit of suspense, part ghost story, part romance. A nice mix that works.The story is about the dig, about learning that there might be more to things than what we just see (and with a nice explanation too), and of course about finding evidence and getting recognition. I think I want to end with a poem :)HE BIDS HIS BELOVED BE AT PEACEby: William Butler Yeats (1865-1939) HEAR the Shadowy Horses, their long manes a-shake,Their hoofs heavy with tumult, their eyes glimmering white;The North unfolds above them clinging, creeping night,The East her hidden joy before the morning break,The West weeps in pale dew and sighs passing away,The South is pouring down roses of crimson fire:O vanity of Sleep, Hope, Dream, endless Desire,The Horses of Disaster plunge in the heavy clay:Beloved, let your eyes half close, and your heart beatOver my heart, and your hair fall over my breast,Drowning love's lonely hour in deep twilight of rest,And hiding their tossing manes and their tumultuous feet.
